Title: Fluorescent type optical fiber probe
Inventor: HIRANO MASAO
IPC: G02B6/00
Filed: 1986-06-18
Abstract: PURPOSE:To correct scattering in characteristics due to the one in mounting an optical fiber bundle and a fluorescent material by covering the material optically coupled with the optical fiber bundle and reflecting excitation light and phosphorescence at a prescribed rate. CONSTITUTION:A core fiber covering 22 and a buffer coating 24 on the distal end of an optical fiber bundle 20 are removed to expose strands 26 and a fluorescent material 28 is joined to the distal ends of the strands 26. The distal ends of the strands 26 and the fluorescent material 28 are covered by a transparent pipe 30 and both are optically coupled with each other. The distal ends of the element fibers 26 and the periphery of the transparent pipe 30 are covered by a film 32. The film 32 is formed by mixing alumina powder in a transparent silicone resin. By adjusting the mixing amount of the alumina powder, the quantity of phosphorescence generated from the fluorescent material 28 by excitation light is adjusted. Thus, the scattering in the characteristics of a sensor due to scattering in mounting the fluorescent material to the optical fiber bundle is easily corrected.

Abstract: PURPOSE:To control appropriately the tension of a rolling material between stands in a multi-strand rolling mill, by calculating the tension between stands from rolling torque and rolling load before and after the material is bitten by a specified stand and correcting the speed of the rolling roll in accordance with the tension. CONSTITUTION:When rolling materials 1-A and 1-B for bar, etc., are rolled at Rows A and B of a multi-strand rolling mill for bar and wire, the tension of the rolling material between stands 1-(i+1) is operated from the rolling torque and rolling load of the stand (i) just before the leading edge of the material is bitten by the stand (i+) in the period after the material is bitten by the stand (i+) until just before the leading edge of the material is bitten by a stand (i+2) and the rolling torque and rolling load of the stand (i) after the leading edge of the material is bitten by the stand (i+1). Then the speed of the rolling roll of the stand (i) is corrected in accordance with the operated result and the tension between stands 1-(i+1) is controlled.

Title: Offset-removing circuit of current sensor
Inventor: MURATA KAZUHIRO
IPC: H02P29/00
Filed: 1994-06-02
Abstract: PURPOSE:To effectively remove an offset voltage with a simple circuit structure by a method wherein an inputted analog signal is converted to a digital signal and an offset value thereof is temporarily held. CONSTITUTION:An A/D converter 1 converts an inputted analog signal to a digital signal to output therefrom. The digital signal is supplied to a memory section 2 and an operation section 3, respectively. The memory section 2 temporarily latches an offset value and when executing the current control of a sub- motor or the like, it outputs the latch data to the operation section 3 in accordance with an adjustment signal supplied from an external section. Then, the operation section 3 subtracts the latch data, i.e., the offset value from the digital signal. As result, the digital signal of which offset value is removed is outputted from the operation section 3. Thus, it is possible to automatically and effectively remove the offset value with a comparatively simple structure.

IPC: H02M1/08
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To obtain an gate output device by which a gate pulse can be output at a correct timing even when a frequency is changed by a method wherein a clock signal which measures the timing of a phase output is corrected by a frequency which is found on the basis of a phase difference. SOLUTION: The output of a VCO 21 is a voltage corresponding to a frequency deviation. The sum of a voltage corresponding to a reference frequency Vo and a voltage corresponding to a frequency deviation Δω from a loop filter 12 is added by an adder 13 so as to be multiplied by a prescribed gain G, and a voltage V corresponding to an input frequency (f) is obtained. When the voltage V is input to the VCO 21, the VCO 21 outputs a pulse which is proportional to the input frequency. When the pulse is used as the interrupt pulse (clock signal) of a microprocessor μC 23, an interrupt pulse interval is changed when the input frequency is changed, and the interrupt pulse which is synchronized with the input frequency is obtained. That is to say, it is divided equally by one cycle No.  The cycle No (pieces/cycle) can be adjusted to an arbitrary value by adjusting the gain G and a frequency divider 22.

IPC: G02B3/08
Filed: 1983-08-10
Abstract: PURPOSE:To enhance performance of a Fresnel lens by forming an optical glass into a Fresnel mold, and when needed, subjecting the surface to transmittance raising treatment. CONSTITUTION:Molten optical glass is poured into the mold of the Fresnel lens, and molded by cooling, or heat softened optical glass is molded with said mold to prepare a Fresnel lens 1. The Fresnel lens thus formed, when needed, is coated with vacuum evaporation deposition, or the like to raise transmittance. Since the optical glass is formed by molding, a glass material high in refractive index can be used and an inclination angle alpha can be made smaller than that of a plastic molded lens, formation using a mold can be made easy. The use of glass materials having various Abbe numbers facilitates the correction of color aberration, too, thus permitting enhancement of Fresnel lens performance.
